Most extension tables require adding leaves, and at best go from being a short rectangle to a longer one. This one by Mauricio Affonso changes shape entirely.
By shifting out base supports in the core frame, more area can suddenly be covered by the table as it bends its top bends into a circular shape.
Or, like a more conventional pull-out variant, frame pieces can be added below while it is pulled apart to simply become a larger and longer table.
“The FAN Table explores the role of tables as the infrastructure for social interaction. Created from over 400 slats, the table can be quickly transformed into an array of different shapes and sizes to suit its context or use. The surface can freely expand, contract and revolve in an effortless fan like movement of the hand. The FAN Table was exhibited at the Royal College of Art ‘s PARADISE exhibition during the Salone Internazionale del Mobile. Venture Lambrate, Milan 2012.”
